Remainder

Greetings of the day…!!!
I had given the task of risk management. I have an excel file where the supplier detail with mail id is provided. Based on Priority I should select the supplier and send them the mail to fill the form and send me back. Once I received the assessment I should scrap the data and write them in excel. Till this I had done. Now, After 3 days I should send the remainder to the suppliers who did not reply to me the assessment form. How can I achieve it? I am completely blank can anyone guide me.

In the same excel file add an extra column Status. Once you receive the email, take the sender email and then in the excel file set status to Done or Completed.

After 3 days, read this excel file and then filter out the data which are not completed and then send email again.

Regards,
